The implementation of copy_user_enhanced_fast_string in the Linux Kernel copy routine uses stac/clac in the epilog and prolog. perf annotate shows the following code:

I'm trying to figure out a homework assignment and I've run into a very specific weird problem. Basically I'm using regex to pull all of the operators and operands out one at a time in order of operations, and then pop them off a stack while printing them in the correct postfix notation. It works in most cases, however when running the unittest it fails test_infix14, test_infix_bad_expression, and test bad postfix. I can tell that it's something to do with the way + and - is coming out of the expression (I think) but I have no idea what's making it do it this way. Any help is appreciated. I thought I had this one good and done on Friday but this one little issue has occupied 2 whole days :P

I have a draggable widget (from https://medium.com/flutter-community/create-a-draggable-widget-in-flutter-50b61f12635d ) with a stack in a container (red color) consists of moveable children. Here is the widget tree:

I wanted to add a Gesture Transformations as FormBuilder ( https://github.com/flutter/flutter/blob/master/examples/flutter_gallery/lib/demo/transformations/transformations_demo.dart ) to transform the matrix, as you can see in the GIF, mainly zoom in/out and transform x/y.

I wish to use a list of date objects into a loop but i do not get the expected output. the function includes parameters on date and currency. The 'time_start' parameter is not working properly. I would like to loop with a list of date that i generate before to call the function but the API send me the following error. I tried to change the format to date object but it is still not working.

error:

I had a TABLE

ID TYPES 1 A \\ 1 B \\ 2 B \\ 3 A \\ 4 A \\ 4 A \\ 4 A \\ 4 C \\ 4 D \\ 4 E \\ 5 B \\ 5 B \\ 6 A \\ 7 A \\ 7 B \\ 7 C \\ 8 B \\ 8 B \\ 9 D \\ 10 A \\ 10 A \\ 10 D

I have TABLE:

ID TYPES
1 A+B \\ 2 B \\ 3 A \\ 4 A+A+A+C+D+E \\ 5 B+B \\ 6 A \\ 7 A+B+C \\ 8 B+B \\ 9 D \\ 10 A+A+D

It was used: let Source = Excel.Workbook(File.Contents("c:\Desktop\stac.xlsx"), null, true), Sheet1_Sheet = Source{[Item="Sheet1",Kind="Sheet"]}[Data], #"Promoted Headers" = Table.PromoteHeaders(Sheet1_Sheet, [PromoteAllScalars=true]), #"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"TYPE", type text}, {"ID", type text}}), #"Changed Type" = Table.TransformColumnTypes(#"Changed Type1",{{"ID", type text}, {"TYPE", type text}}), #"Grouped Rows1" = Table.Group(#"Changed Type", {"ID"}, {{"All Rows", each , type table [ID=text, TYPE=text]}}), #"Added Custom" = Table.AddColumn(#"Grouped Rows1", "Custom", each [All Rows][TYPE]), #"Extracted Values" = Table.TransformColumns(#"Added Custom", {"Custom", each Text.Combine(List.Transform(, Text.From), "+"), type text}), #"Removed Columns" = Table.RemoveColumns(#"Extracted Values",{"All Rows"}) in #"Removed Columns"

But I need to distinct values:

ID TYPES
1 A+B \\ 2 B \\ 3 A \\ 4 A+C+D+E \\ 5 B \\ 6 A \\ 7 A+B+C \\ 8 B \\ 9 D \\ 10 A+D

I'm developing an app for users to share their books. To achieve this, I'm getting different data about the book from the user. The problem is, horizontal autoscrolling of all EditTexts are working until Dialog has been shown and dismissed. Once a dialog has been dismissed on the fragment, horizontal autoscrolling of the EditText's on this layout won't work.

I added:

I get an error trying to convert double to GridLength in star units. The converted itself works fine but I get an error in the runtime

. The strange thing is the converter works perfectly when I use the Absolute unit.

Converter

The objective of this program is to reverse a given string while switching each letter's case. String cannot be longer than 20 characters, if input is longer than that, program requires user to enter string again. Program ends when user inputs 'enter' and the program ends after printing an ending sentence.

Implementing this I have 3 problems:

1. I tried to get input string by using call ReadString and since this procedure stops when enter key is given, the console freeze-ends when I press the enter key to normally finish the program. How could I correct my code to make it print an ending message and then end the program normally with return value 0?

2. If input string is longer than 20 characters, it should require user to input string again. So I wrote ja L1. Bur for some reason, mov bytecount, eax; cmp bytecount, 20; cannot seem to filter the case properly. When the line mov bytecount, eax is executed, the value of bytecount is correct, but when the program executes the next line, cmp bytecount, 20, the value of bytecount changes. I don't know what I'm doing wrong.

3. CaseChange procedure freezes when it is executed, so I guess it's looping infinitely, but I can't find what condition is wrong.

I am implementing a graph class and would like to write a function that determines whether a given path exists.

My graph is represented as {a:{b:c}} where a and b are a vertex connected to each other, and c is the weight of the edge. It is a non-directional graph. I'd like to implement my does_path_exist() function for a non-directional graph. It currently computes as if my graph is directional.
